![]() ![]() ![]() ![]() The relationship between the intracellular fluid compartment, interstitial fluid, and plasma can be seen in this figure. Note that this figure only demonstrates the relative sizes of body fluid compartments and does not provide any information regarding how these compartments are related to one another. In adult women, the total fluid volume is approximately 55% of the total body weight. In adult men, the total fluid volume is approximately 60% of the total body weight. Body fluid volumes in a healthy 70-kg adult male Compartment Volume Subdivisions Intracellular fluid, ICF (2/3 of TBW) 28 L - Extracellular fluid, ECF (Sucrose space) 1/3 of TBW 14 L 10.5 L (Interstitial fluid) Extracellular fluid, ECF (Sucrose space) 1/3 of TBW 14 L 3. All percentages shown in this figure refer to the percentage of the total body fluid volume in an adult human being. Fluid within the body can be thought of as separated into several functional compartments divided by semi-permeable membranes which allow free movement of. Transcellular fluid is found in small amounts in specialized compartments (e.g., cerebrospinal fluid, intraocular fluids, inner ear fluids, pericardial fluid, peritoneal fluid, synovial fluids, etc.). To investigate the influence of Na+ in sweat on the distribution of body water during dehydration, we studied 10 volunteer subjects who exercised (40 of. Interstitial fluid is the fluid that directly bathes the cells and tissues in the body. This compartment can be further subdivided into the interstitial fluid (~25% of total body fluid volume), plasma (~7% of total body fluid volume), and transcellular fluid (~1% of total body fluid volume). The extracellular fluid compartment makes up approximately 33% of the total volume of body fluids. A 70-kg lean man has 42 L of water, assuming the total body water content is 60 of the body weight (70 × 0.6 42 L) 1. This compartment holds approximately 67% of the total volume of body fluids. The ECF compartment, in turn, is divided into the following subdivisions: Distribution of water in various body fluid compartments: ECF extracellular fluid ICF intracellular fluid. The intracellular fluid compartment contains the fluid that is present in the cytoplasm of all cells of the body. As shown in other figures for men and women, body fluids are located in two main compartments: intracellular fluid (ICF) compartment and extracellular fluid (ECF) compartment. ![]()
